Switching device

Abstract

A switching device includes a switch and an actuating element. The actuating element for a switch includes a U-shaped actuating section. The actuating section includes two different arms with different lengths. The long arm is configured to transfer force to a button of the switch and a free end of the long arm is configured for holding the actuating element. The short arm is configured for the force input and is arranged aligned obliquely to the long arm.

The invention claimed is: 
     
       1. A switching device comprising:
 a switch, a push button protruding out from a housing of the switch and configured to be pressed to trigger the switch; 
 an actuating element which is elastic arranged on the switch to operate the push button of the switch upon a force; 
 wherein the actuating element comprises two different arms with different lengths and the two different arms are disposed as a U-shaped shape, a long arm of the two different arms transfers force to the push-button of the switch, a free end of the long arm holds the actuating element; and 
 wherein a short arm of the two different arms is arranged aligned obliquely to the long arm. 
 
     
     
       2. The switching device of  claim 1 , wherein the short arm comprises a bend facing the long arm at the free end of the short arm, in rest position of the actuating element, the bend of the short arm is not touched the long arm. 
     
     
       3. The switching device of  claim 1 , wherein branches are respectively disposed on both sides at the free end of the long arm with supporting portions respectively, turning supporting portions are formed on the housing of the switch correspondingly for holding the actuating element. 
     
     
       4. The switching device of  claim 3 , wherein the supporting portion is a round opening, the turning supporting portion is a circular cylinder, the supporting portion is rotatable sleeved on the turning supporting portion. 
     
     
       5. The switching device of  claim 1 , wherein a return arm is disposed at the free end of the long arm. 
     
     
       6. The switching device of  claim 5 , wherein a receiving groove is disposed on the housing for receiving the return arm. 
     
     
       7. The switching device of  claim 5 , wherein the return arm is formed integrally with the switch housing of the switch. 
     
     
       8. The switching device of  claim 2 , wherein a bend is formed on a central region of the long arm and disposed below the bend of the short arm. 
     
     
       9. The switching device of  claim 8 , wherein the bend of the long arm is formed a step on the long arm. 
     
     
       10. The switching device of  claim 8 , wherein an angle of the bend of the short arm is equal to or smaller than an angle of the bend of the long arm. 
     
     
       11. The switching device of  claim 1 , wherein the actuating element is formed of sheet metal or plastic. 
     
     
       12. The switching device of  claim 1 , wherein the switch is a microswitch. 
     
     
       13. The switching device of  claim 1 , wherein the free end of the long arm is mounted on the switch for holding the actuating element. 
     
     
       14. The switching device of  claim 1 , wherein the free end of the long arm is mounted around the switch for holding the actuating element which is disposed separately from the switch. 
     
     
       15. The switching device of  claim 1 , wherein the short arm extends along a top surface of the switch. 
     
     
       16. The switching device of  claim 1 , wherein the short arm and long arm are disposed substantially parallel. 
     
     
       17. The switching device of  claim 1 , wherein the short arm is formed from an opposed end of the long arm away from the free end, the short arm is extended toward the free end of the long arm from the end of the long arm.
